TY - JOUR A1 - Denecke, Klaus-Dieter A1 - Hounnon, Hippolyte T1 - Partial Menger algebras of terms JF - Asian-European journal of mathematics N2 - The superposition operation S-n,S-A, n >= 1, n is an element of N, maps to each (n + 1)-tuple of n-ary operations on a set A an n-ary operation on A and satisfies the so-called superassociative law, a generalization of the associative law. The corresponding algebraic structures are Menger algebras of rank n. A partial algebra of type (n + 1) which satisfies the superassociative law as weak identity is said to be a partial Menger algebra of rank n. As a generalization of linear terms we define r-terms as terms where each variable occurs at most r-times. It will be proved that n-ary r-terms form partial Menger algebras of rank n. In this paper, some algebraic properties of partial Menger algebras such as generating systems, homomorphic images and freeness are investigated. As generalization of hypersubstitutions and linear hypersubstitutions we consider r-hypersubstitutions.U KW - n-ary operation KW - n-ary term KW - superposition of n-ary operations and n-ary KW - terms KW - linear term KW - r-term KW - Menger algebra of rank n KW - partial Menger KW - algebra of rank n KW - r-hypersubstitution Y1 - 2021 U6 - https://doi.org/10.1142/S1793557121500923 SN - 1793-5571 SN - 1793-7183 VL - 14 IS - 06 PB - World Scientific CY - Singapore ER -
